Indiana University of Pennsylvania Late Paleozoic Sedimentation Patterns and Paleoenvironment Reconstructions in the Northern Appalachian Foreland Basin

KUSHNER, B. and SCHIAPPA, T.A., Department of Geography, Geology and the Environment, Slippery Rock University, Slippery Rock, PA

A complex network of fluvial systems filled the Appalachian Foreland Basin from a variety of provenance regions during the Late Mississippian-Early Pennsylvanian periods (325-315 Ma). This basin formed in response to the accretion of the Taconic, Avalonian, and Acadian terranes and the collision of paleocontinents Laurentia and Gondwana, forming the Alleghenian orogen. Previous research of immature fluvial systems along the orogen compared U-Pb dated mineral ages to known provenance regions of various tectonic ages on Laurentia. These studies concluded that sediments were transported into the adjacent Appalachian Foreland Basin from the Acadian and Taconic terranes, uplifted Precambrian Greenville basement, and Canadian Shield. This research compared the contribution by these sediment sources along the orogen to their contribution along the northern shoreline of the Appalachian Foreland Basin, sampled in Venango County, Pennsylvania. Petrographic analysis and paleocurrent data were used to interpret paleoenvironmental changes between sandstone units. Point count compositional data was plotted on QFL diagrams to compare provenance of each unit. Based on our results a fluvial model for this section of the basin was produced. This research indicates that mature fluvial sediments comprising subsurface strata in northwestern Pennsylvania originated primarily from the Alleghenian orogen during the Late Mississippian-Early Pennsylvanian periods. Future research will include U-Pb mineral dating to quantify sediment contribution by minor provenance regions during these periods, as well as analysis of older rock units to determine when provenance and paleoenvironment changes occurred. Understanding these sedimentary trends is integral to safe and efficient resource extraction and geologic modeling of other foreland basins in .

Molecular Dynamics Simulations of Sequestration in Depleted Shale Gas Reservoirs

KAZEMI, Mohammad, Department of Petroleum and Natural Gas Engineering West Virginia University, Morgantown WV

With large scale production of gas from shale resources, large volumes of pore space have been recently vacated. Therefore, there is a huge capacity of carbon dioxide (CO2) that could be stored. Furthermore, due to the higher affinity of the organic nanopores to CO2 compared to methane, injection of CO2 can enhance the recovery of natural gas. The objective for this work is to investigate displacement and sorption (adsorption of CO2 and desorption of methane) in organic nano-capillaries using Molecular Dynamics simulations.

In this study, sorption capacity of two adsorbing gases (methane and CO2) is compared by performing Molecular Dynamics (MD) simulations in identical setups of carbon nanotubes. MD simulations are performed for different capillary sizes, pressures, and temperatures. Excess and absolute adsorption isotherms of these gases are plotted and compared. To simulate the displacement process, methane molecules are initially adsorbed on the walls of the nanotube. Then, CO2 is injected to replace the methane molecules. Finally, composition profiles of pure CO2 displacing methane with time are examined.

(continued on next page)

According to MD simulation results, adsorption capability of CO2 is found to be higher under the same pressure and temperature. As pore size increases, the adsorption structure of methane changes from single layer to multilayer adsorption. As the temperature increases, the amount of adsorbed molecules for both gases decreases. It is found that the CO2 molecules replace adsorbed methane molecules due to their higher adsorption capacity. A slow breakthrough and sharp front is observed in this displacement process. The results show that the amount of CO2 storage and methane production rate are increased as CO2 injection pressure increases. Furthermore, the rate at which CO2 could be injected is higher than the rate of methane production.

Effects of Hurricane Joaquin on the Sandy Hook Washover Fan Complex on San Salvador Island, Bahamas

SCACCHETTI, J.L., ZALLER, M., and YOVICHIN, R.D., Department of Geological and Environmental Sciences, Youngstown State University Youngstown, Ohio 44555

San Salvador lies along the eastern edge of archipelago. Forty-seven hurricanes and tropical storms have impacted the island in the last one hundred and forty five years with four major hurricanes striking the island since 1996. The combination of storm frequency, little commercial development of the island and near-shore inland lakes makes San Salvador an ideal location for the study of ancient storms or paleotempestology. The work presented here is part of on-going paleotempestology research on the island.

The most recent storm to hit the island is hurricane Joaquin, which made landfall on October 2, 2015, as a category four hurricane having a maximum wind speed of one hundred and thirty five knots. Being an island with little development, the physical impacts of recent hurricanes may remain in place for many years. Long-term records of hurricanes may be preserved in the sediments of near-shore lakes present along much of the island’s coast. The sediments of one lake located near Sandy Hook along the southeastern coast of the island (23⁰56’52.54”N, 74⁰30’28.36”W, WGS 84) that have shown evidence of past hurricanes was impacted by hurricane Joaquin in the form of a large wash over fan deposit that transported marine sand a distance of approximately 140 meters inland. The research presented here focused on this wash over fan as an effort to characterize this type of storm deposit and to better understand ancient storms in general.

The research is based on the premise that inland lakes are dominated by non-marine gradual fine sediment and organic deposition and the presence of marine sand deposits within a lake is evidence of ancient storms. In order to characterize the lake deposits and the over wash fan, a total station survey was performed for survey location and elevation control, sediment core and auger samples were collected to sample and characterize the lake deposits and ground penetrating radar transects were performed to better define the contact between lake deposits and the underlying bedrock. The collected data was integrated using Arc GIS 10.3 in an effort to show the lateral extent and depth of the material deposited by the storm. Student Poster Presentations

At least one student from each research team will be present during the 6:00-7:00 social hour to discuss their research project and answer any questions.

THE ORIGIN OF WESTERN PENNSYLVANIA PLACE NAMES

Although Jumonville, on the crest of Chestnut Ridge near Uniontown in Fayette County, refers specifically to a Methodist camping and retreat center, generally speaking the whole area is referred to as Jumonville. It was named for Joseph Coulon de Villiers de Jumonville, an ensign in the French marines. Jumonville was in charge of a troop of Canadian and French soldiers sent to discourage a company of Virginia militia and Indian allies, commanded by Lieutenant Colonel George Washington, from attempting to protect workers building a fort in French-claimed territory at the forks of the Ohio River (later known as Pittsburgh). A large band of French soldiers had chased the workers away and began building Fort Duquesne at the forks. Washington and his small band were on their way to the site when they encountered Jumonville and his men. The battle, which lasted only 15 minutes on May 28, 1754, became known as the Battle of Jumonville Glen. Jumonville Glen, site of the beginning of the French and Indian War

Ten French soldiers were killed outright, and 21 were captured, including Ensign Jumonville who was carrying diplomatic papers. Although he was being treated honorably as a prisoner of war, without notice, one of the Indians walked up to Jumonville and killed him with a tomahawk while Washington stood by dumbfounded. After these events, Washington and his men retreated to nearby Fort Necessity where they eventually surrendered to Canadian forces from Fort Duquesne. The terms of Washington's surrender included a statement in French (which Washington could not read) stating that Jumonville had been assassinated. Washington, in his journals, gave no details of the incident, so the exact circumstances of Jumonville’s death are still controversial to this day.

The Battle of Jumonville Glen is credited as the opening salvo of the French and Indian War, The event, as brief and seemingly innocuous as it was, also had international repercussions – it is credited with starting the Seven Years War, the real first world war. The Seven Years War lasted from 1756 until 1763, and was fought by every major European power across North America, Europe, Africa, and Asia. And the beginning of it happened right at the top of Chestnut Ridge, one of the very few major anticlines found in western Pennsylvania

DID YOU KNOW . . . ? temperatures such as in the present deep ocean. show a remarkable resemblance to those known Although many researchers believe that Earth's from more recent ice ages. The researchers early oceans were very hot, reaching as much as believe this indicates that the Earth experienced 176oF, new research from South Africa indicates an extensive, possibly global, ice age about 3.5 that both the land and the ocean were much billion years ago. Although they don’t expect the colder than that.

Until this study, the Paleocene-Eocene of causing extinctions before humans showed up. Thermal Maximum (PETM), which occurred around 56 million years ago, was the largest carbon release since the became extinct.

But now, according to the new data, the PETM was much smaller than the current input of carbon to the atmosphere. The maximum sustained carbon release rate during the PETM was estimated to be less than 4 billion metric tons of

CO2 per year. By comparison, the 2014 carbon- release rate was a record high of about 37 billion Pleistocene megafauna – was metric tons of CO2, about ten times the PETM or human hunters to blame for their extinction? estimate. As such, the current carbon-release rate is unprecedented in Earth's post-Mesozoic The researchers used statistical correlations history, so there is no analogue that can be used between sudden warming events (interglacials) to determine what will happen in the future. and the extinctions of large animals. They pointed out that the interglacials were the single biggest magnitude change in climate to have occurred in the past 2 ma, with temperatures rising as much as 10oC in just a few decades. That kind of climate change would cause huge disruptions in weather patterns and vegetation growth.

Of course, there are still many researchers who feel that humans were to blame. For example, Researchers used the JOIDES Resolution to about 50 genera went extinct in South America take deep sea cores across the PETM interval during the time of the Wisconsinan glaciation in the northern hemisphere, yet there were few if any The researchers’ study indicates that we are in extinctions in Africa at that time, even though the uncharted territory when dealing with the rate of climate was probably similar to that of South carbon being released into the atmosphere and America. As the idea goes, humans had been oceans. And, if the PETM is any indication, the hunting in Africa for 2 ma and their prey were consequences of our massive fuel burning adapted to the predatory pressures. South will have a much, much longer tail. While the America, however, had just recently (geologically world seems to be focused on what the Earth will speaking) been invaded by human predators and be like in 2100, what happens after that is had not had time to adapt before going extinct. anyone’s guess. Life arose on Earth something less than four Finally, someone has decided what the worm-like billion years ago. And according to the prevailing creature called Tullimonstrum gregarium must dogma, life appeared because Earth had a rocky have been in life. The Tully Monster, as it has surface, liquid water, a blanketing atmosphere, been dubbed, is the official state fossil of Illinois, and warmth. Now, thanks to a new research, we having been collected from the Pennsylvanian can say the Earth’s magnetic field probably Francis Creek Shale at the famous Mazon Creek played, and continues to play, a key role in collecting locality in that state for decades. It has making the planet conducive to life. even appeared in paintings on the sides of U-Haul trucks. Eugene Richardson named the fossil in 1966 for Francis Tully, the person who collected it, but he was so unsure of what it represented that he simply filed it under “animal”. Some folks thought it was a bizarre worm, others some kind of snail, and the nut cases even suggested it was an early relative of the Loch Ness Monster. No one was could decide conclusively where it belonged in the tree of life.

Now an international team from the Sun’s powerful solar winds and flares of researchers believes they have figured out The new research involved studying Kappa Ceti, a what this mystery critter was. Having looked at star located 30 light-years away in the more than 1,200 specimens of the fossil, the constellation Cetus.

The clue to 400-600 million years old, meaning it formed this relationship lay in a pale line visible on the sometime between the Late Neoproterozoic and that stretched from the eye stalks to the Early Devonian when complex life was evolving end of the tail. The researchers recognized this on Earth. Like other stars its age, Kappa Ceti is as a notochord, which made Tullymonstrum a very magnetically active, with a surface blotched vertebrate rather than an invertebrate.

There is a new detailed gravity map of Mars, a new study indicates that the many species now thanks to three NASA spacecraft, and it is going the way of the Great Auk and the Dodo may providing a glimpse into the hidden interior of the vanish with no permanent record of their ever planet. The new gravity map should be helpful for having been here.

It took two years of analysis and computer modeling to remove the motion not caused by gravity. But it was worth it. The improved resolution of the map will help scientists better understand the as yet unknown formation of certain areas of Mars. Improved resolution of Mars’ gravity map suggests there is a new explanation for how some features formed on the planet. Also, the team studying the NASA data confirmed that Mars has a liquid outer core of Which ones are most at risk of having no record? molten rock.

Fun Fact Having Nothing to Do with Geology

Analysis of 15 separate studies in Europe found that myopia (near-sightedness) is becoming more common there, with the increase linked to education level. This suggests that reading and working with computers is at least one contributing factor.
